Fault TolerantServers

Express5800/ft series

“Why choose a server designed to recover from

failure rather than a server designed not to fail in the first place?”

SourceVernon Turner - IDC, 2001

what is a fault tolerant server
What is a Fault Tolerant Server ?

Duplication

Duplication

Duplication

1/ It contains fully replicated redundant subsystems

2/ It is designed to eliminate any single point of failure and safeguard data integrity.

The server automatically manages its redundant subsystems,

executing all processing in lockstep.

Replicated subsystems perform the same instructions

at the same time, with instantaneous failover to the redundant system should a problem occur.
